SAUSAGE LINKING OR TWISTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 589,578, datedSeptember *7, 1897. Application filed April 28, 1897. Serial No.634,214. (No model.)

To aZZ whom it mdy concern;

Be it known that I, \VILLIAM F. SCHGN- LAND, a citizen of the UnitedStates, residing at Manchester, in the county of Hillsborough and Stateof New Hampshire, have invented certain new and useful Improvements inSan: sage Linking or Twisting Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to means for parting, linking, or dividing afilled sausage-casing into connected sausages of the desired length.This has commonly been done by hand, but it consumes quite a little timeto link a fullsaved greatly increased profit to the manufacturer wouldresult.

To this end the object of my invention is to provide a machine whichwill accurately divide filled sausage-casings into sausages of anydesired length more rapidly and better than it can be done by hand.

The invention consists in the novel feeding, clamping, and twistingmechanism, as fully set forth in the following 'speciiication and claimsand clearly illustrated in the drawings accompanying and forming a partof the same, of which- Figure l is a front elevation of my improvedmachine, Fig. 2 being a general plan view. Fig. 3 is an. enlargedelevation showing the clamping and twisting mechanism in detail. Figs. 4and 5 are enlarged details of portions of the clamping mechanism. Fig.(i is a broken plan view showing the twisting-rolls with portions of thecarry-*ingbelts and of a filled sausage-casing, all in proper relativeposition and on an enlarged scale. Fig. 7 is an elevation showing indetail one of the carrying-belts with its guides and pressure roll andhaving the sausage in dotted lines. Figs. 8 and 9 are enlarged broken.elevations illustrating the gripping and twisting mechanism.

Similar referencedetters indicate like parts in all the views.

To carry my invention into effect, I provide carrying-belts andtwisting-pulleys running at right angles to each other, as will beshow-11 and described. These carrier-belts are arranged to move thesausage-casingtoa proper position to be clamped at each side of thetwistingrolls and then to stop while the clamps and twisting-rolls dotheir work, when said carrier-belts again start in motion.

Referring to the drawings by letters, A re presents a suitable base orframe upon which my machine is set up.

B is a driving-shaft supported in bearings b and carrying tight andloose pulleys h and at each end a beveled gear-segment C, which move thesausage-carrying belts by meshing with the beveled pinions D, mountedupon counter-shafts E, supported in bearings e e and carrying each apulley F. At the proper point between these shafts E are bearings g,which carry a roll G, the sausage-carrying belts H being each passedaround a pair of these pulleys or rolls F G, as seen in Figs. 1 and 2,one of which belts is provided with grooved clips or rests h, securedthereon at regular intervals and at proper distances apart to equal thelength of the sausages which are being passed over the belts, thusinsuring the movement of the sausage and the belts in unison; but themovement of the sausage-casing must discontinue at intervals long enoughto part or divide and twist them into'the desired length, and for thisreason I remove the teeth from a portion of the beveled gears C 0, thusleaving the blank surfaces 0, as the shaft B moves continuously, to

provide for revolving or twisting the sausage while its longitudinalmovement is discontinued. One simple means of accomplishing this isshown in the drawings, and consists in part of a pair of rolls I, placedadjacent to but not. in contact with each other and located between therolls G and at right angles therewith, the journals of said rolls Ibeing equidistant from the longitudinal center of the belts H and theproper height to cause a sausage X, when spanning the space between thebelts H, to come in contact with both said rolls I, which are caused torevolve in like direc tion one with the other by means of sprocketwheelsK 70 and a chain L, the sprocket K being mounted on the shaft B and thesprockets 70 on the journals 2' of the rolls I, idlers k being carriedon one of the standards or bearings J, so as to cause the chain to passover the sprockets 7.: at the proper angle to perform its function.

The other essential features in connection with the rolls I are thesausage compressing or linkingjaws, which may be bent, as shown, so asto cross each other when performing their work. A pair of these jaws onmay be placed one at each end of the rolls I and be operated toward andaway from each other by any convenient means so long as such operationoccurs at the proper time to cause the jaws to hear at opposite sides ofthe sausage X the moment its longitudinal movement ceases, theircompression to continue until the meat within the sausage-casing shallhave been pressed to either side of said jaws m, which divides thesausages into the required links. A pressure-roll N, which is carried inloose bearings a, formed upon or attached to one of each pair of jaws m,bears down upon the sausage-easing with sufficient force to cause it tobe rapidly revolved by means of the rollsI, upon which it rests, whichtwists the casing between said jaws and at the points indicated bydotted lines in Fig, 6 to a small size, as seen in Figs. Sand 9.

The clamping-jaws 711 may be variously operated, this being effected ina simple manner when attached to or formed upon the ends of bars M,which are shown in the drawings pivotally attached to a shaft P, carriedin bearings 0, said bearings also carrying another shaft P, the outerends of which are provided with a laterallydisposed bar 19, its endsextending at opposite sides of said shaft. These bars 19 rest betweenthe rear ends m of the bars M, normally in the position seen in Figs. 3and 5, but when the shaft P is rotated the ends in of the bars M arespread, as seen in Figs. 3 and 4, which movement causes the jaws m toclose tightly upon the sausage-casing, as seen best in Figs. 3, 8, and9. In order to give to this shaft P the slight rotative movementrequired at the proper time, a suitable cam Q may be attached to theshaft B and adapted to operate an arm R, carried upon the shaft P, asseen best in Figs. 4 and 5, and in order to normally hold the bars Mapart, so as to keep the jaws on separated, a helical spring m may beattached to ends m of the bars M, as clearly shown in Fig.

The sa11sagecasii1g and divided or linked sausages X may be guided inpassing upon the belts II by the guides S, those serving the purpose forthe belt having the link-clips 7L, being provided near one end withsuitable ears 3, in which are formed vertically-elongated openings .5,forming bearings for the journals of apressureroll 'l, as shown in Figs.1, 2, and 7, which assists the adhesion of the sausageoasing to thecarrier-belt.

Having described my invention, what I Claim iS 1. In a sausage-linkingapparatus, a pair of rolls placed adjacent to each other and rotatingboth in the same direction, a suitable sausage-clamping device at eitherend of said rolls, and suitable means for intermittently moving a filledsausage-casing across said rolls.

2. In a sausage-linking apparatus, a pair of intermittently-inovablesausage-carriers, a pair of rolls both rotating in the same di reotionplaced adjacent to each other at right angles'with and between saidsausage-carriers, and a suitable gripping or sausage-cla1nping device ateach end of said rolls.

8. In a sausage-1inkingapparatus horizontally-movable sausage-casingcarriers, a pair of rollslocated between and revolving at right anglestherewith, a pair of jaws adapted to divide or compress thesausage-casing at each end of said rolls, and means for moving saidcarriers intermittently, substantially for the purpose set forth.

4. In a machine of the character described. suitable belts adapted tocarry sausage-casings longitudinally and to move intermittently, a pairof linking-jaws, and suitable rolls rotating in a course at right angleswith said belt and between said jaws and adapted to twist thesausage-casing into the required links.

5. In a machine of the character described, a pair of carrier-beltspassed each over a pair of pulleys, both belts running in longitudinalalinement and at opposite ends of a sausage twisting and clampingmechanism. said twisting and clamping mechanism, and suitable rests orclips attached to one of said carrier-belts for receiving the links ofthe sausage-casing.

In testiinony'whereof I affix my signature in presence of two witnesses.
